PURPOSE:To be able to miniaturize a bottom frame and eliminate the damage to insulating material despite rough handling by a method wherein the lower parts of heat exchanger fixing plates combined with fin fixing plates are brought into contact with the insulating material and a drain pan is attached to the exchanger fixing plates and a shielding plate cutting off draft is also placed. CONSTITUTION:Insulating material 17 is sticked on the overall surface in the inside of a bottom frame 11 formed in box shape. At the one side of longitudinal direction of a drain pan 10, an L-shaped shielding plate 18 is fixed and the lower one side of the plate 18 is in contact with the upper surface of the material 17. At the both sides of a heat exchanger 9, fin fixing plates 12, heat exchanger fixing plates 14, and side plates 15 are fixed with screws 13, 15 to hold the exchanger 9 and also fix the pan 10. As a result, the material 17 is able to be sticked inside the frame 11 and the heat of the plate 18 fixed to the pan 10 is not transmitted to the bottom frame and under blast flowing from either of right and left directions, blast leakage does not take place. |
